The Projector-Augmented-Wave method The number of plane waves needed to describe • tightly bound (spatially strongly localized) states, • and rapid oscillations (nodal features) of the orbitals near the nucleus exceeds any practical limit, except maybe for Li and H. The common solution: • Introduce the frozen core approximation:

11.5 Fermi Energy in Metals The Fermi-Dirac distribution implies that at absolute zero (in the ground state of a system) the largest Fermions (electrons, holes, etc.) are filled up in the density of states, of which the energy is often called the Fermi energy (Figure 11.5), but here we specifically redefine it as the Fermi energy at absolute zero.

Where Does the Density of States Concept come from? Approach: 1. Find the smallest volume of k-space that can hold an electron. This will turn out to be related to the largest volume of real space that can confine the electron. 2. Next assume that the average energy of the free electrons (free to move), the fermi energy E f

If we have N electrons, at T = 0, the electron occupies the lowest N’2 states. The energy of the highest filled state is known as the Fermi energy eF. The momentum of this state is known as the Fermi momentum PF. The wavevector of this state is known as the Fermi wavevector kF. Obviously, PF = ÑkF and eF = (6.13) PF 2 2 m = Ñ2 k F 2 2 m

The symmetric stretching fundamental (0) E100 and the interaction energy F will be calculated from equations 6. Coefficients c1 and c2 for the mixed states ψ+ and ψ− can be calculated from the secular equation plus the normalization condition.

We can therefore take the unit of force as 1 kilogram 1 metre/second2. We call this by the name, Newton for convenience. The unit of energy is Newton-metre.
